Sorry about the delay in response guys. I'm only about 350 miles in on the new rack. Over those 350, the VDC hasn't turned off once nor has any other issue arose. I beat on it up and down the canyon a number of times, respectively of course, some city driving and highway.
I believe I've mentioned it, but I also did a whole suspension upgrade so the whole car feels totally different. I cant really say what the steering rack alone did. Not only that, but I've also had the car torn apart for a so long comparison between old and new would not be accurate. I can say that I love how the steering feels. The wheel is very responsive. Like most other people lower speeds is harder turning but once moving over 5ish mph it feels very smooth.
It seems like there's a little air in the system as it does shudder every once and a while at low speeds. No bubbles in my tank so it isn't a leak. I did turn the wheel from side to side, many times, while jacked up. I think it just has to naturally bleed over the course of driving it a little while. The shudder has gotten less frequent from when I first took it out and never has happened at higher speeds. My blinker also functions normally, shutting off after a turn.
I have yet to get it aligned. My dad and I spent a long time making sure everything was close so I could safely get some mileage (500) on the suspension before alignment. He worked in a small town garage in his younger years so he had some low tech methods of getting everything close. And damn its pretty spot on for staying straight on the road. But I don't know what problems could arise from an alignment so I'm going to say its likely good to go in my VDC car.
I'll continue to update. I don't drive the car much in the winter because my job comes to a halt first snow of the season. Thank god you can't pour concrete in the cold. So we're able to go to a one car family and I get to play stay at home dad. But like I say, I'll continue to update once the miles start getting racked up.
